What is Genotype Ratio?

The Genotype ratio refers to the proportion or distribution of the different genotypes within a population. Genotype represents the genetic composition of an individual specifically the combination of the alleles (alternate forms of a gene) that an organism possesses for the particular trait.

Formula for the genotype ratio

Genotype Ratio = Number of the individuals with a particular genotype / Total number of the individuals in population

In genetics, alleles can be dominant or recessive, and they determine the expression of the traits in an individual. The genotype ratio describes the relative frequencies of the different genotypes within a population and is often derived from a Punnett square or by analyzing the inheritance patterns of the specific alleles.

Example:

Let’s say you have 100 individuals in a population and 25 individuals have the genotype AA, 50 individuals have the genotype Aa and 25 individuals have the genotype aa.

The genotype ratio would be:

Genotype Ratio (AA) = 25 / 100 = 0.25 or 1:4

Genotype Ratio (Aa) = 50 / 100 = 0.50 or 1:2

Genotype Ratio (aa) = 25 / 100 = 0.25 or 1:4

Difference Between Phenotype and Genotype Ratio

Understanding the difference between phenotype and genotype ratio is essential in genetics. While phenotype refers to observable traits influenced by genotype, genotype represents the genetic makeup of an organism. Unraveling this distinction sheds light on inheritance patterns and genetic variability. Explore the phenotype and genotype ratio to grasp their significance in evolutionary biology and hereditary trait inheritance.
